It's about +0.05 to +0.07 for my CPU for each 100 MHz around the voltages that are interesting. It seem to need a bit more around 1.4V. So if your CPU behaves a bit like mine, if you are sure the 1.29V are the lowest stable for 4.9, I'd guess 1.35V or 1.36V for 5 GHz. That should still be a pretty conservative voltage. Using offset overclocking, any spikes in voltage would still be below 1.4V, I'd think.

Adding 0.04vcore isn't much for 100mhz, it's actually very little when near 5ghz. Often people have to add 0.12v for 200mhz, to get from 4.5 to 4.7 for example.

There are hundreds of people who would be pushing towards 5.1 or 5.2 24/7 with such a chip, just to let you know thumb.gif 1.29vcore is kinda conservative. Not really conservative even, but kinda average, as 1.25-1.3vcore is a pretty standard overclock

Agreed, if I had that chip I would def be running it at 5Ghz. 1.35 is nothing really. Even up to 1.4.

I'm running 1.33 for 4.7Ghz and I'm not the least bit worried about this level of volts. Only reason I'm not running 5Hz is because I need almost 1.5 volts to stay there and 1.5 might be a bit too much. So no dice for me, 5.0 at 1.35 or even 1.38 is totally within the realm of safety IMO.

Remember the only time its really pushing those volts are at start-up and when you are gaming or benching. The rest of the time its loafing along at about 1.08v....

you run 1.33v on air/aio cooling? do you live somewhere cold lol?
post #565 of 615
Hm, didn't know it needed that mutch "more" to just gain 100hz, that is also the reason I said not worth it. But if you guys saying saying that I need even more, then I might try more. Cause I just really want to reach 5ghz (so mutch better number than 4.9)

Btw, I got a 360 and 240 radiator with a wc 7970, so it's not on air:-P

h80i to be exact. Temps never get above 72C. Ambient temp is 25C. That's running Prime95. During gaming its in the mid 60's. I am delidded though, so keep that in mind.

I'd say that this is totally safe. IMO

I wouldn't hesitate to put 1.4v to it if I could get 5ghz. But it won't do that, I tried. Max I could get at 1.4 was 4.9Ghz and it really needed about 1.42 to be 100% stable. Thus why I settled at 1.32 and 4.7ghz. The temps kinda went crazy at 1.4v too. Mid to high 80's. Not too bad, but higher than I want to be long term.

I think i need to reseat my h100i then.

I'm at 4.5 @ 1.22v, ambient 25C

75C in prime95, 79C in IBT

Back on 2500K this chip would have been considered decent I think but now I'm starting to think it's utter crap considering it's stable at 5.1GHz / 1.52V...

Are you delidded? If so, then I'd say yes try that mount again.

I noticed about a 4C drop when I went to Phobya HE grease. That's what I use on TIM and IHS mount. Good stuff.

How long have you been running at 1.52v?

What are you temps like on the Phobya?
